Yes Wal-Mart does carry the NEF in .410. I see them everytime I go by the case. They run about $80.00. They also carry them in 20ga. I bought one of the 20s and love it. I'm thinking of getting a .410 barrel for it just for the fun of shooting a .410. I haven't shot one in many years. Your question has gotten me missing those 410s. If she's small you might think about getting one of the Rossi Matched Pairs. They're a little more expensive but they are a little smaller than the NEF youth models. The NEFs are a lot smoother and tighter though.
